TECHNICAL FIELD

The present disclosure relates to a system to monitor and control operation of a pool system including pool components, and in particular to such a system that includes a visual light communication system.

BACKGROUND

Visual light communication (VLC) is a data communication medium that uses visible light between 400 THz (780 nm) and 800 THz (375 nm) as an optical carrier for data transmission and illumination. It uses fast pulses of light to transmit information. Light emitting diodes (LEDs) are one type of light that can be used in VLC. LEDs can be turned on and off quickly and perceived as a continuous beam of light. This is because the reaction time of the typical LED is less than 1 microsecond, which cannot be detected by the human eye. The change from an “on” state to an “off” state in high frequencies enables data transmission. “On” states and “off” states (represented as “1” and “0” respectively) can be encoded as data. Signal processing can be used to process that encoded data into information useable in a variety of contexts.

SUMMARY

An embodiment of the present disclosure is a visual light communication (VLC) system. The VLC system includes a light transmitter operable in water of a pool system. The light transmitter is configured to repeatedly transition between an on configuration where light is produced and an off configuration where no light is produced in order to generate a light signal that passes through the water. The transmitted light signal has encoded therein information concerning a pool component. The system also includes a light sensor operable within the water in the pool to receive the transmitted light signal. The light sensor is configured to convert the transmitted light signal into an electronic signal.

Further, the software applications can be implemented across computing devices arranged on a network that includes aspects of a client-server network, peer-to-peer network, ring-type network, and/or other network architectures known to a person of ordinary skill in the art. Accordingly, it should be appreciated that numerous suitable alternative communication architectures are envisioned.

FIG. 5 shows an embodiment communication system 30 implemented using visual light communication assemblies 50 a and 50 b. The communication system 30 includes a first visual light communication (VLC) assembly 50 a and a second visual light communication (VLC) assembly 50 b positioned across a water gap W. The first visual light communication (VLC) assembly 50 a includes a light transmitter 52 a, a light sensor-receiver 54 a, a communication assembly controller 56 a, and a power source 58 a. The light transmitter 52 a may communicate with a sensor receiver 54 a in the first VLC assembly 50 a and with a sensor-receiver 54 b in the second VLC assembly 50 b.

The light transmitter 52 a can be an LED on one side of a water gap W and the sensor-receiver 54 b can be a photo diode on the other side of a water gap W. The light transmitter 52 a is configured to repeatedly transition between an on configuration where a light is produced and an off configuration where no light is produced. The repeated transitions between the on and off configurations generate a transmitted light signal having encoded therein information concerning a pool component of a pool system. The sensor-receiver 54 a is configured to receive the transmitted light signal from a different transmitter.

In accordance with the illustrated embodiment, the light transmitter 52 a can be a high-brightness white LED. The sensor-receiver 54 a can be a silicon photodiode that is responsive to a visible wavelength. The sensor-receiver is configured to function as a receiving element. Embodiments of the present disclosure allow for using mixtures of red, green, and blue LEDs to provide the opportunity to alter the light frequency encoding to a different data channel. In one example, data files of at least 256K have been transmitted up to 10 meters through turbid water with minimal data loss. This data point is not limiting but is illustrative. Data files may be transmitted more than 10 meters with minimal data loss. The system as described herein may be to retrofit pre-existing LED lighting systems to allow for simple interactive functional commands between lights. These commands can be read by a computing device in proximity to the LEDs. Alternatively, the commands can be transmitted remotely via wireless communication channels.

The controller 56 a is electronically coupled to the transmitter 52 a and the receiver 54 a. The power source 58 a supplies power to the controller 56 a, the transmitter 52 a, and the receiver 54 a. The controller 56 a may include an encoder 57 a and a modulator-demodulator 59 a (and/or demodulator-modulator 59 a). The controller 56 a may include signal processing instructions, firmware, communication protocols, and/or other applications that operate signal transmission between the transmitter 52 a and the receiver 54 a and between different communication assemblies. The communication assembly 50 a may include a plurality of transmitters 52 a, receivers 54 a, power sources 58 a, and/or communication assembly controllers 56 a. Furthermore, the transmitter 52 a and receiver 54 a can be configured as a transceiver, a transmitter-receiver, or any other device for processing input and output signals. In such an example, the transmitter is configured to switch the light source on and off in order to generate a signal having encoding therein data.

The first VLC assembly 50 a includes a power source 58 a. A number of different power sources 58 a may be used. For instance, the power source 58 a can be batteries or power generators. For example, the power generators can be flutter type that include a body configured to oscillate or move in response to fluid flow and generate a voltage based on said oscillations. In another example, the power generator can be a body with an inner surface, an outer surface, a winding at least partially disposed along the outer surface, a passage, and a moveable element disposed in the passage and moveable relative to the body so as to generate a voltage in response to fluid flow through the body.

The second visual light communication (VLC) assembly 50 b includes a light transmitter 52 b, a light sensor-receiver 54 b, a communication assembly controller 56 b, and a power source 58 b. The light transmitter 52 b may communicate with a sensor receiver 54 b and with a sensor-receiver 54 a in the first VLC assembly 50 a. The light transmitter 52 b can be an LED on one side of a water gap W and the sensor-receiver 54 a can be a photo diode on the other side of a water gap W. The controller 56 b is electronically coupled to the transmitter 52 b and the receiver 54 b. The power source 58 b supplies power to the controller 56 b, the transmitter 52 b, and the receiver 54 b. The controller 56 b may include an encoder 57 b and a modulator-demodulator 59 b (and/or demodulator-modulator 59 b). The controller 56 b may include signal processing instructions, firmware, communication protocols, and/or other applications that operate signal transmission between the transmitter 52 b and the receiver 54 b and between with other communication assemblies 50 a. The second VLC assembly 50 b may include a plurality of transmitters 52 b, receivers 54 b, power sources 58 b, and/or communication assembly controllers 56 a. Furthermore, the transmitter 52 b and receiver 54 b can be configured as transceiver, a transmitter-receiver, or any other device for processing input and output signals. In such an example, the transmitter is configured to switch the light source on and off in order to generate a signal having encoding therein data.

The second VLC assembly 50 b includes a power source 58 b. The power source 58 b can be batteries or power generators. For example, the power generators can be be-flutter type that include body configured to oscillate or move in response to fluid flow and generate a voltage based on said oscillations. In another example, the power generator can be a body with an inner surface, an outer surface, winding at least partially disposed along the outer surface, a passage, a moveable element disposed in the passage and moveable relative to the body so as to generator a voltage in response to fluid flow through the body.

Continuing with FIG. 5, in operation data is transmitted via a light transmitter 52 a into pool water W in the form of a light signal S1. The light signal S1 passes through an optional lens (not shown) covering into the water W until it reaches anther optional lens (not shown) covering the sensor-receiver 54 b in the second VLC assembly 50 b. The received light signal is converted back into data and sent to the communications hub 40 and relayed to the computing device 20 for further processing. Furthermore, data may be transmitted via a light transmitter 52 b of the second VLC assembly 50 b in the form a light signal S2 to the sensor-receiver 54 a of the first VLC assembly 50 a. The received light signal S2 is converted back into data and sent to the communications hub 40 and relayed to the computing device 20 for further processing. The light transmitters 52 a and 52 b and sensor-receivers 54 a and 54 b can be communication with each other. Furthermore, each light transmitter 52 a, 52 b, . . . 52 n may be configured to emit a signal at a defined transmission angle. Each sensor-receiver 54 a, 54 b, . . . 54 n may be configured to emit a signal at a defined transmission angle that is wider than the transmission angle of the light transmitter 52 a, 52 b, . . . 52 n. This feature can maximize the ability of multiple sensor-receivers to capture a light signal regardless of the alignment of the light transmitter and the sensor-receiver within the water gap W.

FIGS. 6 and 7 illustrate alternative configurations for implementing visual light communications in a pool environment. In the illustrated embodiment FIG. 6, data is encoded and modulated via the controller 56 a before being sent to light transmitter 52 a. Furthermore, the light transmitter 52 a may have different color transmitters, such as a red transmitter 62, a green light transmitter 64, and a blue light transmitter 66. The signal is received by the sensor-receiver 54 b in FIG. 6. The signal is then decoded and demodulated in controller 56 b. Alternatively, as shown in FIG. 7, each sensor-receiver 54 b has sensors 72, 74, and 76 that correspond to the different light transmitters 62, 64, and 66. The data can be encoded and modulated via the controller 56 a and then split among the different light transmitters 62, 64, and 66 as shown in FIG. 6. Alternatively, the signal can be parsed into groups before being encoded and modulated. Upon receiving the signal by the sensor receiver 54 b, the signal may be demodulated and decoded via controller 56 b. Each signal group is then transmitted from a separate light transmitter. Accordingly, the sensor-receivers receive each signal group and decode and demodulate each group separately before re-combining the groups together to re-form the entirety of the transmitted information.

The VLC communication assemblies described here are configured as send-receive assembles. Each send-receive assembly, or VLC assembly, therefore includes the at least one light transmitter and at least one sensor. Each VLC assembly is configured to A) transmit a respective transmitted light signal, and B) receive a respective one of the transmitted light signals from a different one of the plurality of send-receive assemblies. The VLC assembly may be disposed along one or more of the pool system components. Alternatively, the VLC assembly may include a light transmitter and another VLC assembly may include a sensor-receiver such that individual VLC assemblies are configured for send functions or received functions.

FIGS. 8-10 illustrate an exemplary hardware implementation of the VLC assembly 50 a, 50 b. The VLC assembly 50 a may include a housing 90 having a first portal 92 that contains the transmitter 52 a and a second portal 94 for the sensor-receiver 54 a. The light transmitters 52 a may include a red transmitter 62, a green light transmitter 64, and a blue light transmitter 66, and a lens 92. The sensor-receiver 54 a includes multiple photo-diodes and a lens 94. Within the housing 90 is a PCB 96 including circuitry, the controller 56 a, and power source 58 a. The housing 90 may be adapted to couple to a pool system component, such as return line or nozzle and the like.

FIG. 11 illustrates a method 700 of using the visual light communication among one or more pool components. The method 700 may be implemented using computing device 20 and one or more VLC assemblies 50 a, 50 b . . . 50 n. As shown in FIG. 11, in step 702, pool data is obtained for example via sensor or other monitoring device. In step 706, the light transmitter 52 a transmits the light signal within pool water. Step 706 may include signal processing, such as encoding and modulation of the data into the light signal. In step 708, the sensor-receiver 54 b of a second VLC assembly, also submerged in water, receives the transmitted light signal through the pool water. However, in step 710, the signal transmitted in step 706 may be received by multiple VLC assemblies. In step 712, the transmitted light signal can be relayed to the communications hub 40. The communications hub 40 may include a receiver submerged in water so as to receive signals from the VLC assemblies 50 a, 50 b under water. Other components of the communications hub 40 relay the pool data to the computing device 20. Accordingly, methods described herein are suitable for communication from an underwater communication to a location that is external to the pool water, as described above. Examples include, but are not limited to, direct water-to-air communication, and/or indirect water-to-air communication. The system may include a VLC system as described above and one or other communications systems or protocols to enable data collected within the pool to be transmitted to a computing device external to the pool. Furthermore, the systems as described herein can be used to transmit inputs, commands, or control instructions from a computing device external to the pool system to parts of the VLC system and/or a computing device associated with the VLC and the pool components. Accordingly, for signals traveling between two non-similar fluids, the transmission is not hindered.

The VLC assemblies in method 700 may transmit data at different speeds. In one embodiment, uploading and processing a signal using VLC creates no significant lag, resulting in substantially instantaneous transmission and analysis. In a further embodiment, uploading and processing analog or digital signaling using indirect VLC and adaptive modulation may incur a time lag, thus not being substantially instantaneous. An advantage of such an embodiment is use in data transmission that is not highly time-dependent. This may decrease costs associated with using such an embodiment, for example manufacturing costs, installation costs, and operation costs. Such an embodiment may be well-suited for use in swimming pools or similar environments.

Continuing with FIG. 11, in step 716, the computing device 20 can adjust operation of a pool system component. For instance, step 716 may include causing, via the computing device, a mechanical or electrical action of at least one of the plurality of pool components in response to information encoded in the transmitted light signal. A mechanical response may be movement or transition of a state of one or more pool components. Electrical responses may include processing, powering up, powering down, etc.

Embodiments of the present disclosure are suitable for controlling operation or monitoring the state of one or more pool components of a pool system. An exemplary method 800 for monitoring and controlling a pool system is shown in FIG. 12. The pool components may include, but are not limited to, a water pump, return lines, return fitting, return jets, pool filter, motor, skimmer, and pool lighting, a chemistry analyzer. Embodiments of the present disclosure include a system that has the ability to communicate certain data regarding conditions including, but not limited to, temperature, chemistries, flow rates, and pressures. An embodiment may also be configured to initiate and transmit commands to control different aspects of the pool system environment, including, but not limited to, fluid circulation, lighting, and chemical balancing.

Referring to FIG. 12, step 802 of the method 800 includes obtaining data for one or more of the pool system components. Step 806 includes transmitting pool data via a VLC assembly, at least a portion of which is in pool water. Step 808 includes transmitting the compiled information concerning the one or more of the pool system components to a computing device. The method can further include in step 812 analyzing the information concerning the one or more pool system components. Step 816 includes displaying the information concerning one or more of the pool system components on a user interface running on the computing device. In step 816, the computing device 20 can adjust operation of a pool system component in response to an instruction from the computing device to alter the state the pool system component.

Referring to FIG. 13, embodiments of the present disclosure have VLC assemblies with functionality that allows for receiving and processing signals within water in a variety of pool layouts and configurations. The VLC assemblies are configured to transmit, receive, and analyze data from refracted or scattered light. An advantage of such an embodiment is that the light transmitter can be directed at the sensor-receiver at larger angles. For instance, as illustrated in FIG. 13, a light transmitter of a first VLC assembly 50 a can be positioned along a common axis A1 that is directly across from a sensor-receiver of the second VCL assembly 50 b. The light transmitter 52 a of first VLC assembly 50 a can be positioned at location that is offset from the sensor-receiver of a third VLC assembly 50 c aligned along an axis A2. Furthermore, each light transmitter 52 a, 52 b, . . . 52 n may be configured to emit a signal at a defined transmission angle α. Each sensor-receiver 54 a, 54 b, . . . 54 n may be configured to emit a signal at a defined transmission angle αr that is wider than the transmission angle at of the light transmitter 52 a, 52 b, . . . 52 n. This feature can maximize the ability of multiple sensor-receivers to capture a light signal regardless of the alignment of the light transmitter and the sensor-receiver within the water gap W. Thus, data transmission can occur regardless of whether the light transmitter and the sensor-receiver are positioned along a direct, linear path with respect to each other or if they are not positioned along a direct, linear path.

An embodiment of the present disclosure may have a program or application that allows a user to select which pool component to monitor and control. The program can utilize any suitable method of selecting a pool component or set of pool components. For example, the user may select the desired component from a displayed list or grid of components. The components can be displayed in any suitable layout.

In one example as shown in FIG. 14, the user may point an imaging device connected to a computing device 40 to a portion P of pool 422. The computing device 422 can then obtain information concerning pool components within that portion P of the pool 422 and display their status on the computing device's user interface. Alternatively, the user can select a pool component based on proximity to the computing device 20 being used. For example, if the computing device 20 is within a predetermined vicinity of the return 10 c, the computing device can display the return 10 c and status information regarding the return 10 c. If the user would like to control operation of the return 10 c, the user interface displays control inputs that can be used to control one or more operation of the return 10 c. Alternatively, any other acceptable method of selecting a component from a group of components can be utilized in the program or application.

Embodiments of the present disclosure may include a system that can react to changes that occur within the pool environment. Examples of automated control of pool components include, but are not limited to, lighting, heating, surface skimming, pump activation, and drain valve activation. Such a system could react to various stimuli, such as, for example, the presence of users in the pool, the chemical analysis of the water, presence of a foreign object, and other internal or external environmental factors.

Data communication with the use of VLC can be affected by various factors. These factors may include, but are not limited to, light wavelength attenuation and absorption, turbidity of the fluid medium, motion on the surface of the fluid, chemical composition in the fluid and interaction of the chemical components, presence of bubbles or particulates in the medium, transition of the signal from water-to-air or air-to-water, reflection or refraction of light in the fluid, and the maximum range of the light transmitter components. Other factors may include, but are not limited to, placement of light-emitters and light-receivers with respect to one another, internal or external power sources for operating the components, levels of signal noise, conversion of analog-to-digital or digital-to-analog signals, underwater and above water signal processing components, the presence of a time lag in transmitting, receiving and analyzing signals, and external controls (such as computers or smartphones). Embodiments of the present disclosure include different variations intended to address one or more of the above-mentioned factors to facilitate acquisition, processing, and use of pool data.

Embodiments of the present disclosure also include the ability of a pool communication system as described in any of the above embodiments to interact with components already present in the pool system, such as lights, pumps, drains, valves, heaters, vacuums, and all other components common to swimming pool use and maintenance. A further embodiment also has the ability of the pool communication system to interact with external components not within a pool system. For example, the VLC system in a pool may interact with external components in a nearby building or vehicle.
